. ARRANGEMENT FOR THE BETTER EXHAUST AND USE OF THE EXPLOSION OF THE MOTOR GAS IN ORDER TO OPERATE AN ALARM BELL.

Application filed February 18, 1926, Serial No. 89,240, and in Argentina December 1, 1925.

This invention has reference generally to improvements in signalling devices and more particularly relates to a bell signalling attachment for the exhaust pipe of a motor vehicle.

It is the primary aim and object of this invention to provide a device of the above mentioned character which is designed to be interposed in an exhaust pipe and embodies manually operable valve means for operating in connection with a diaphragm carrying signal so that when the valve means is actuated to vpartly close the exhaust the signal will be simultaneously operated to sound an" alarm to warn pedestrians of the approach of the vehicle 7 More particularly the invention embraces the provision of a device of the above mentioned character wherein the casing is constructed so as to be fitted in exhaust pipes of various diameters while the valve chamber is formed so that the valve may be readily inserted therein.

Other objects as well as the nature, characteristic features and scope of the invention will be more readily apparent from the following description taken in connection with the accompanying drawing and pointed out in the claims.

The invention is clearly illustrated in the accompanying drawing, in which Fig. 1 is a top plan view showing the invention applied to an exhaust pipe,

Fig. 2 is a longitudinal vertical section taken on line 22 of Fig. 1 in the direction in which the arrows point,

Fig. 3 is a fragmentary horizontal sectional view through the arrangement, the diaphragm and the clapper being shown in plan,

gig. at is a perspective detail of the valve, an 7 Fig. 5 is a fragmentary perspective detail showing a form of spring for holding the diaphragm against the aperture in the casmg.

Similar characters of reference are employed in all of the above described views to indicate corresponding parts.

Referring now, more particularly to the accompanying drawing there is provided a casing 1 which is preferably cylindrical and which is provided with a longitudinal bore 2 the outer surface of the body being re- -tice the casing is provided with a cylindrical chamber 5 which is formed at right angles to the bore 2 opening from the upper surface of the casing and terminating to the opposite surface thereof. It is preferred that the medial portion of the casing be square in cross-section so as to permit of the formation of the cylindrical valve chamber. Revolubly mounted in the chamber is an improved valve body 6 which includes upper and lower disc-like portions 7 connected by a web 8 which is arcuate in cross-section, the substantially opposed longitudinal or vertical edges being provided with semi-circular recesses 9. Normally these recesses are adapted to lie in substantial alignment with the edges of the bore 2 but upon partial rotation of the valve body in a counterclockwise direction the outer outlet end of the bore 2 'is partly closed by the adjacent portion of the web 8 so that some of the exhaust gases are directed through a secondary outlet 10. Disposed in front of the outlet 10 and yieldably connected to the side of the casing is a diaphragm 11 which carries a suitable sounding or signalling device for instance in the form of a bell 12 and a clapper 13, the action of the gases against the diaphragm causing ashaking of the clapper and a consequent sounding of the bell to warn pedestrians or other motorist of the approach of the vehicle. Suitable means in the form of a spring 14 is employed for yield-ably mounting the diaphragm over the opening 10.

Means for operating the valve and consequently controlling the operation of the bell preferably consists of a radially extending arm 15 connected with the upper disc 7 of the valve body, a suitable connection 16 being fastened to the outer end of the arm and operable from a point adjacent the drivers seat to rock or partially rotate the valve body. Suitable means such as a coil contractile spring 17 has its respective ends connected to the arm 15 and the main casing 1. It is apparent that a pull on the element 16 will partially rotate the valve body 6 and upon the partial closing of the outlet end (if'th'e bore 2 some of the exhaust gases consequently pass through the sec'on'dz'i'ry outlet 10 shaking the diaphragm 11 and thereby sounding the bell.

- It is belie ved that in view of the foregeinga further detailed description of the operation of the invention is entirclyunnecessary. Likewise it believed that the advai'itages oi the invention will be readily apparent. V

l'l'avingthus fully described the invention What is claimed as new and desired to be secured byLetters Patent is 1. zr s'ignalling attachment for the exhaust pipe of a motor vehicle including a casing provided with a longitudinal bore -nd a valve chamber intersecting the bore and having a secondary outlet leading therefrom, a valve rotatably mounted in the chamber for partially closing the outlet phragni and adapted to be actuated by the vibration of. diaphragm.
